February 17, 2015 — Underscores has become the go to tool for many theme developers, as their starting point when creating a new theme. It’s the semi-standard for the WordPress.org Theme Repository, and the origin for all themes launched on WordPress.com in the past three years. In this presentation we’re taking a look back at its origins, its successes, and most importantly, its most recent improvements. Including a feature update that supercharges Underscores.me, and will change how developers will interact with WordPress starter themes for years to come.
